The grammar of some foreign languages ??is very special. The nouns are actually verbs, such as pencil, pen, and ballpoint pen. Can they be understood as writing?

1. Answer: In language learning, we often encounter the linguistic phenomenon that a word is both a noun and a verb. This is not only found in English, but also in Chinese. In English grammar, this method of word formation is called conversion method, which is to convert the same word from one part of speech to another.

2. Expansion: It is impossible for any language to create unlimited new words to express new ideas. On the one hand, this is because people's memory capacity is limited, and on the other hand, this approach is not feasible in language practice. Therefore, the vocabulary in the language always follows the principles of convention, simplicity and economy, so that a word has multiple meanings or multiple parts of speech. Common word-formation methods in English include synthesis, derivation, transformation and abbreviation, of which derivation and transformation are the two most important. The so-called derivation method is a method of adding an affix before or after a certain word to form a new word. What is added at the front is called a prefix, and what is added at the end is called a suffix. Prefixes often change the meaning of words, and suffixes often only change the part of speech. Take the common suffix -ly as an example. ① Add to the noun to form an adjective: brother - brotherly, friend - friendly, sister - sisterly. ② Add to adjectives to form adverbs: beautiful - beautifully, nice - nicely, real - really, finally - finally. The transformation method is to combine the same words. One part of speech is transformed into another part of speech. For example, water, the noun means "water"

, and the verb part of speech means "watering, watering". The noun spring means "spring" and the verb means "jumping".

3. Example:

① How sweet the water is! How sweet the water is!

What are you doing now? I'm watering the garden. What are you doing now? I'm watering the garden.

② We have been good friends for years. We have been good friends for more than ten years.

May the friendship between Chinese people and French people last for ever.
